How to Implement LiteSpeed Cache for WordPress

Improving your WordPress performance doesn’t need to be complicated. With LiteSpeed Cache, you can speed up your website noticeably and create a smoother experience for your visitors. This guide walks you through every step for you to set up LiteSpeed Cache quickly and enjoy faster load times right away. 

What Is LiteSpeed Cache 

Caching stores copies of your site content, so users can access them faster. Since LiteSpeed Cache works on a server level and integrates deeply with LiteSpeed or OpenLiteSpeed it goes even further than an average caching system. It handles full-page caching and advanced optimization features, which together deliver a powerful performance boost. 

Step 1: Check Server Compatibility 

Before installing the plugin, make sure your hosting runs LiteSpeed or OpenLiteSpeed. You can check this in your server information or ask your hosting provider. On the Contabo VPS, LiteSpeed is not pre-installed, yet you can set it up easily if you want to use it. 

Step 2: Install the Plugin 

Now head over to your WordPress dashboard. Then go to Plugins → Add New, search for LiteSpeed Cache, and install it. After installation, click Activate to enable the plugin. 

Step 3: Enable LiteSpeed Cache 

Once activated, navigate to LiteSpeed Cache → General. Switch Enable LiteSpeed Cache to ON. This connects WordPress to the server-level caching engine and improves your page performance immediately. 

Step 4: Optimize Page Load Settings 

Next, move to LiteSpeed Cache → Page Optimization. Then enable three key settings: 

  • Minify CSS and JavaScript 
  • Load CSS asynchronously 
  • Defer JavaScript 

These options reduce file sizes and ensure that your page content loads faster. 

Step 5: Optimize Images and Use QUIC.cloud 

To improve performance even more, open the Image Optimization section. There you can activate QUIC.cloud, a free service that compresses images and converts them automatically to WebP. This reduces image weight and speeds up page delivery. 

Step 6: Use CDN and Test Your Results 

Under the CDN tab, enable QUIC.cloud CDN or connect your preferred CDN. A CDN distributes static files across global servers, helping your site load quicker for visitors worldwide. After enabling your CDN, use tools like GTmetrix or PageSpeed Insights to measure your performance improvements. 

Final Tip: Confirm it Is Working 

To confirm that LiteSpeed Cache works correctly, open your website in incognito mode. Right-click and select View Page Source, then scroll to the bottom. If you see:

Your caching setup is active and running.
